REGISTER- Application filed August 11, 1925. Serial No. 49,538.

This invention relates generally to heating apparatus and refers moreparticularly to hot air registers designed for use w1thin vehicle bodiesand.tl1e like.-

One of the essential objectsof the invention is to provide a neat andcompact register that may be manufactured for a com-. paratively lowcost and can be easily and quickly installed within a vehicle body andthe like. Another objectv is to provide a register'of this type thatpreferably consists of relatively few parts which may be readilycleaned, repaired or replaced when desired.

.A further object is to provide a strong anddurable register having anair supply passage and a dirt outlet whlch are controlled by a singlevalve that may be easily and conveniently actuated by simple andreliable operating means.

With the above and other objects in view, the invention consists ofcertain novel features of construction, combinations and arrangements ofparts as will be more fully described and particularly pointed out 1nthe appended claims.

In the accompanying drawings:

Figure 1 is a'fragmentary side elevation of a vehicle body with aregister embodying my invention mounted thereon.

Figure 2 is a top plan view of the register.

.Figure 3 is a vertical sectional vlew through the register. 1

Figure 4 is a horizontal sectionthrough the register.

Figure 5 is a vertical sectional view taken at right angles to thesectional view shown in Figure 3.

Figure 6 is a detail top plan View of the actuating pawl. a

Referring now to the drawings, the numeral 1 designates a register forcontrolling the passage of hot air from a suitable heater 2 to theinterior of a vehicle body 3. As shown, the register is preferablylocated 1n the floor 4 of the vehicle body and 1s connected to theheater 2 by means of a suitable conduit 5. In detail, the registercomprises a tubular body or casing 6 and apertured cover 7. As shown,the casing 6 1s provided at one side thereof with an air inlet opening 8surrounded by a tubulanfitting 9 connected to the air supply conduit 5and is provided at its upper end with a flared portion 10 thatterminates in an annular flange 11. The cover 7 has an annular portion12 that surrounds and is preferably welded to the flange 11 of thecasing 6. To'provide a neat joint, the floor 4 of the vehicle body isprovided with an opening 13 to recelve the annular portion 12 of thecover, while the latter is preferably provided at the lower edges of theannular portion 12 with a lateral flange 14 that is secured to the lowerface of the floor 4.

Located within the casing 6 is a disk valve 15 that is adapted tocontrol the passage of air from the conduit 5 to the interior of thevehicle body. As shown, this valve 5 is rigidly secured to a pivot pin16 journaled in the side Walls of the casing 6 and is adapted to bemoved on said pivot from the position shown by full lines to theposition shown by dotted lines in Figure 5 0f the drawings for directingthe hot air portion 22 above the pivot 16 and to a lug 19 secured to thecasing 6 at the lower end thereof. Thus, with this construction, thesprin 18 will urge'the valve 15 to open or closed positions afterthevalve is moved beyond dead center and will be effectively held by saidspring in such open or closed positlons.

For actuating the valve 15, I preferably provide a pawl 20 having anopen ended slot 21 receiving the crank portion 22 of the pivot pin 16and having a vertical opening 23 for receiving the shank 24 of ahorizontally extending operating handle 25 disposed above the cover 7.As shown, a bracket 26 secured to the casing 6 supports the pawl 20which in turn is held on the shank 24 ofthe operating handle by means ofa cotter pin 27 1ocated preferably beneath the bracket 26. It will alsobe noted that the opening 23 in the pawl 20 is rovided with a flat side28 that is engage by the correspondingly flattened portion 29 of theshank 24, hence\the handle 25 is non-rotat- -ably connected to the pawl20, however the handle to open position shown by right or left by thehorizontal manipulation'o-f the handle 25 above the "register cover 7.As a result, the crank portion 22 of the pivot pin.16 will be rocked toopen or close the valve 15.

In use, the valve 15 may be moved byfthfi lines in Figure 5 or may bemoved to closed position shown by dotted lines. When in open positionthe h t air from the conduit 5 will be directed by the valve 15 throughthe apertured cover 7, while in closed position the hot air will bedirected downwardly through the open lower end of the casing 6.

Inasmuch as this opening 17 at the lower end of the casing is inalignment with the open upper end thereof, it will also be apparent thatdust, dirt, in fact sediment of aa kind collecting or finding its way inthe casing 6 will readily fall through the lower opening I 17 when thevalve 15 is moved from open to closed position. Hence, this form ofregister may be easily and quickly cleaned. Moreover the operation ofthe movable parts is exceptionally simple and dependable. It will alsobe apparent that the parts of the register may be readily assembled andthe vehicle body having an opening therein, of

ended body located in said opening and havan air register comprising anupright open ing a lateral inlet opening for air below the flooring, anda valve in the body opposite to the inlet opening alternately adjustablefrom a position inclined upwardly from the lower 2. The combination witha-vehicle body having an opening therein for air, of an air registercomprising a body located in said opening, said body havingsubstantially aligned outlet openings for air and an inlet opening forair intermediate said outlet openings, a perforated cover for said body,a 'valve in the body opposite to the inlet opening alternatelyadjustable from a position inclined upwardly from the .lower edge ofsaid opening to a position inclined downwardly from the upper edge ofsaid opening, the arrangement being such that foreign matter andsediment falling through the perforations in said cover into said bodywill be discharged from said body when said valve is in a positionintermediate the inclined positions aforesaid. I

3. The combination with the flooring of a vehicle body having an openingtherein, of an air register for vehicle bodies comprising -a bodylocated in said opening and projecting a short distance below saidflooring, said body having vertically aligned outletopenings for air anda lateral inlet opening for air intermediate said aligned outletopenings, and a disc valve pivotally mounted in the body opposite tosaid inlet opening, said valve being constructed and arranged in such away that it may be moved on its pivot from a position inclined upwardlyfrom the lower edge of said opening to a position inclined downwardlyfrom the upper edge of said opening.

In testimony whereof I aflix my signature.
